Some systems has the IPV6 protocol disabled, so we failed starting up
with the error "Address family not supported by protocol" (#52).
Now we don't exist even if we can't insert the needed rules, we'll just
log the error.
We must intercept RELATED packets, not only for intercept protocols like
ftp-data, but also to handle connection errors (ICMP errors), like the
ones originated when dis/connecting from a wifi network.

We start receiving notifications from the UI, which allow us to change
configurations and perform actions on the daemon.
The concept of Node has also been introduced, which identifies every
daemon (client) connected to the UI (server).
These options has been added:
- Enable/Disable firewall interception (for all nodes)
- Change daemons (clients) configuration. globally or per node.
- Change prompt dialog options.
We have fixed some bugs along the way:
- Close audit client connection gracefully.
- Exclude our own connections from being intercepted.
- Better handling of client connection status with the UI.
We probably has also introduced some other bugs (not listed here).
Sometimes the INPUT rule for to queue DNS responses was not deleted.
The code has also been reorganized.
And a minor tweak to make an if{} more idiomatic.
